Spark plug gap

What is the spark plug gap for an 87 with a 5.0 {305} engine? I think it is 40 degrees. And what is the timing set at? Thanks .

Re: Spark plug gap

Spark plug gap is .035 (In thousandths of an inch). Only the timing is measured in degrees and it is spec'ed at 0 degrees on both automatic and manuals transmissions for your truck.
